SIDAC
(95 - 330 Volts)

General Description
The Sidac is a silicon bilateral voltage triggered switch with
greater power-handling capabilities than standard diacs. Upon
application of a voltage exceeding the Sidac breakover voltage
point, the Sidac switches on through a negative resistance region
to a low on-state voltage. Conduction will continue until the cur-
rent is interrupted or drops below the minimum holding current of
the device.
Teccor offers the complete voltage range (95-330) over three dif-
ferent packages:
•

•
TO-92 (95-280 volts)
Axial lead DO-15X (95-280 volts)
Surface Mount DO-214AA (95-280 volts)
TO-202AB (190-330 volts)
